HEATER AND VENTILATO R.

SPECIFICATION formingpart of Letters Patent No. 235,486, dated December 14, 1880.

Application filed March [3, 1880. (No model.)

To all whom it may concern Be it known that I, HANS J. ANDERSEN, of Spring Valley, in, the county of Fillmore and State of Minnesota,have invented certain new and useful Improvements in Ventilating and HeatingBuildings; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figurefl of the drawings is a representation of a sectional 'plan view of my improved heater Fig. 2 is a sectional detail view of the same; and Fig. 3 is a sectional view of a house, showing my device applied. Fig. 4-.is amodification of the invention, showing the branch pipe entering the roomnear the floor, and the foul-air escape located near the ceiling.

The nature of my invention relates to means for supplying the various rooms of a building with pure warm air, and also for ventilating the said apartments.

The drawings illustrate means for heating and ventilating three rooms, although, as will be seen, more rooms can be heated and ventilated by the same system of devices.

Let A represent the chimney, and B the centrally-arranged smoke-flue, into which the stove-pipe 0, from a stove or furnace in the cellar or first story, opens near its base. The flue B is surrounded by as many pipes or warm air-fines D as there are rooms to be warmed and ventilated.

The flue B passes through a box, E, and from this box rise the pipes D, which surround the smoke-flue B. Fresh air is supplied to this box by a pipe, E, leading to the exterior of the building, and this air is warmed within said box and in the pipes D by the heated smoke-flue, which passes through it. This warm air then ascends upward through the pipes D, and from them is conveyed into the several rooms of the building by the branch pipes F, which lead from said pipes through the chimney" and open into the said rooms aroom and in providing a pipe which eon- 6o ducts away the foul air from the lower part of the room is not, however, new with me, the same having been done in other apparatus for heating and ventilating rooms of buildings. In some instances the heated air has been introduced into the lower part of the room. I shall adopt either plan in applying my apparatus to a building, although I have shown only the first one.

In some cases, instead of cutting off and closing a single pipe, D, just above the point whereits branch pipe leads into a room, the pipe may be extended up so as to serve two rooms by providing it with a valve, D, which may be closed for a while, so as to cause the warm air to pass into one room, and then opened, so as to admit the air into the room above it.

What I claim, and desire to secure by Letters Patent, is-

As an improvement in heaters and ventilators for buildings, the chimney A G, having the smoke-flue B, adapted to be connected with a stove or furnace arranged therein as shown, in combination with the box IE, coldair flue E, and the warm-air flues D, having branch pipes F, constructed and operating substantially as and for the purposes set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
